When you select Power Management – > Allocation in the web interface it shows the power consumption numbers for various server components. It also shows the total consumed by the server.
There are two anomalies in the displayed results:
The display does not show all the components in the server. For example, it does not show processor modules.
As a result, the sum used by the (displayed) components is less than the total used by the system.
This is not really a problem. The Allocated Power figure shows how much power the server is using.
